Re: Adding Drives Mid Project

[Benoit Melancon <ben(at)centrenad.com>]

Hello Ken,

To add to Andi's comments, purchasing a identical array with similar 
drives (I'm guessing from your post that you presently have the 
Ultra320), it would be possible (but to my knowledge NOT officially 
supported)  to take six drives out of the 12 existing ones and exchange 
them for 6 of the new array. You could then have two separate 12-drives 
striped sets spread across two chassis, hence allowing a dual-bus 
connection to both sets and retaining the optimal 2-streams real-time HD 
that you presently have.

This use to be an old Mediadock LVD trick and I never tried it myself, 
but I believed several users did so successfully... Brandon Bussinger 
had a documented exchange with support to that effect a while ago, which 
can be found here:

Hope this helps

Benoit
